ABSTRACT:
Lubricating oil pumps for internal combustion engines have hitherto had individual drive means such as a pair of skew gears. To simplify and cheapen the pump drive means, the pump is of the internal gear type and is driven by and housed within an idler gear driveably connecting the crankshaft to the camshaft. The pump body is rigidly secured to the engine and has a cylindrical periphery on which the idler gear is journalled, and the externally-toothed inner gear of the pump is driveably connected to the idler gear by a coupling sleeve.
